1. When you mix 10.0ml of ascorbic acid standard solution in the flask with 25ml water, 2ml of 6M acetic acid solution and 1ml of starch solution, it is necessary to know the exact final volume of this solution to get an accurate determination of ascorbic acid in the titrations of test solutions? Explain. Hint: Do the volumes o

I have a chemistry problem. In lab we did the experiment Recrystallization. I would like to know if my values that I got in the laboratory are sensible and my percentage recovery. The mass of my impure aspirin was 0.250mg. My volume of solvent used for my impure aspirin was 3.25ml. I got this value from my 2.50ml of water used a

The difference between methane and methanol is an -OH group replacement of a H group. What difference does the -OH group make in this case? Whats the potential for exposure, the most likely exposure routes, and the toxicity effects with it?

If you can remember back to a discussion and inquiry we exchanged last week concerning the use of sodium carbonate vs. calcium carbonate. If you'll recall we were theorizing as to why differing amounts of carbonate in a titration experiment were needed to raise the pH of a solution from 4.0 to 5.0.
When we assumed 100% solubi

An actual lab titration of a mildly acidic process water at a pH of 4.0 requires 0.9 grams/liter of Na2CO3 to raise the pH from 4.0 to 5.0; re-running the titration but this time using CaCO3 requires 2.2 grams/liter of CaCO3 to raise the process water pH from 4.0 to 5.0...essentially a 2.25X difference.
If we assume these tit

I have a wood chemistry course in which we are asked to explain the hierarchy of the organic wood acids present in softwood species like pine or spruce.
Could you please offer a few other possible organic acids that might be present in softwoods? I am only really interested in the predominant acids.

1) When organic acids are subjected to continuing increases in temperature, and depending on the acid itself, is it reasonable to assume that organic acids convert first to aldehydes, then to alcohols, then to alkanes given increasing temperature? It is also a fair assumption that condensing of these compounds would occur in the

Pretend that you are running the following experiment as outlined attached.
1. Prepare 100 mL of 5.0% (w/v) D-glucose solution. Fill the polarimeter cell with the solution. The cell is 10 cm in length. The polarimeter is set at 586 nm.
2. Zero the polarimeter on air.
3. Measure the optical rotation every five minutes and rec

2. The spicy flavor of cayenne pepper is due mainly to a substance called capsaicin. See if you can deduce the structure of each intermediate on the basis of the capsaicin laboratory synthesis.

This problem asks to use equations to outline feasible synthetic routes to the compounds below starting with benzene or toluene and any other necessary aliphatic or inorganic reagents. Assume o- and p- isomers can be separated.

One of the first methods that was used for determining the relative orientations of substituents on aromatic rings was devised by Korner. The "Korner Method of Absolute Orientation" was first applied to determine the structures of the three isomeric dibromobenzenes A, B, and C. Each isomer can be converted into one or more mon

Assuming that you have formaldehyde, CH2O, fully solubilized in water at a temperature of 200 degrees F, is the first order and natural reaction:
CH2O + H2O = CH4O2
In otherwords, assuming that the water is pure water, will formaldehyde with 100% certainty become methylene glycol?
What things might inhibit the formation

In this experiment, I investigated the reactivity of primary and secondary alcohols toward oxidation with sodium hypochlorite (bleach). There were 3 possibilities: 1) only the primary alcohol is oxidized to the aldehyde (carboxylic acid); 2) only the secondary alcohol is oxidized to the ketone, or 3) both alcohols are oxidized.

Metabolism uses various ways to ensure that 2 opposing pathways do not occur at the same time. For the following pair of pathways list 2 ways (different cell location, allosteric effector, covalent modification, different intermediate, different enzyme, or different means of transport).
How are fatty acid oxidation and fat

The purpose of this experiment was to see which mixtures smelled like wintergreen.
The 8 esters and the reactants (alcohols and carboxylic acids) from which they will be
made are shown in Table 1. We checked the smell mixtures by using odor. Two, and only two, of the mixtures should smell like wintergreen (they contain met
